When the product of a series of enzyme catalyzed reaction is able to slow down the speed of the reaction the enzyme is under what kind of control?
Homework Answers
When the product of a series of enzyme catalyzed reaction inhibit the speed of the reaction, the type of inhibition is called Product inhibition.
This is a type of negative feedback control of metabolic pathways.
At low substrate concentration, it resembles competitive inhibition.

Under what circumstances does an enzyme catalyzed reaction rate resemble a non-enzyme catalyzed reaction? At very low concentrations of substrate (Km is greater than S) the Michaelis-Menton equation can be simplified to? At very high concentrations of substrate, the Michaelis-Menton equation can be simplified to? How do you determine the initial rate of reaction

Uncatalyzed Catalyzed Enzyme-substrate Complex In the above reaction, the lower curve is an enzyme-catalyzed reaction where the activation energy is notably lower than the uncatalyzed reaction. Suppose the enzyme in the diagram was mutated in such a way that its affinity for the substrate increased 100 fold, thereby affecting the enzyme-substrate complex portion of the curve. Assume that there was no other effect. Would you expect the reaction rate catalyzed by the altered enzyme to be faster, slower, or equal...
